I love this. Much easier than my previous favorite (also listed here): echo "expr" | bc

Thanks! I created command "calc" from this that I can use from the command line at any time (faster than echo "equation" | bc) ~/bin/calc #!/bin/bash ARG=("[email protected]") x=$( printf "%s" "${ARG[@]}" ) calc(){ awk "BEGIN{ print $* }" ;} calc $x
